Abstract (en)
[origin: US2019334587A1] A method of a user equipment (UE) for a channel state information (CSI) feedback in a wireless communication system is provided. The method comprises receiving, from a base station (BS), CSI feedback configuration information including a number (K0) of coefficients for the CSI feedback, deriving, based on the CSI feedback configuration information, the CSI feedback including K1 coefficients that are a subset of a total of Q coefficients, wherein K1≤K0 and K0<Q, and transmitting, to the BS, the CSI feedback including the K1 coefficients over an uplink channel.
